Title: Original position keeping unit of spring rear face grinding wheel in spring grinding machine
Inventor: WATANABE SHIGERU
IPC: B24B47/22
Filed: 1984-07-03
Abstract: PURPOSE:To always perform excellent spring grinding work by keeping the top face of a spring rear face grinding wheel at almost the same level as the absolute datum surface which is at the same level as the spring placing plane of a machine body. CONSTITUTION:When the increasing amount of spring height of a coil spring 86 after being ground excesses the allowable maximum amount, the upper end of the coil spring 86 after being ground comes into collision with a disk member 16 forcing to move it up. The supporting shaft 14 forced to be moved up makes a swing arm 8 swing around an arm 12 counter-clockwise turning a switch 18 on to output pulse signals. The output shaft of a hydraulic rotary cylinder 62 is rotated in a predetermined direction by a predetermined rotary amount on the basis of these pulse signals to rotate a screw shaft 66 through a clutch 64 in an engaged condition caused by turning on by a level sensor 82 raising a spring rear face grinding wheel 70 by a predetermined amount. And, then, actuation of a hydraulic rotary cylinder 38 rotates a screw shaft 48 to lower a spring top face grinding wheel 58 by a predetermined amount automatically compensating the distance between grinding wheels to a predetermined amount. As a result, a spring 86 is satisfactorily ground.

Filed: 1979-10-25
Abstract: PURPOSE:To remove sine-wave pulsating voltage at a neutral point of a boosting rectifying circuit bt a mechanism wherein variable capacitors are mounted among each output terminal and the neutral point of the circuit. CONSTITUTION:Balance resistors R1, R2 and variable capacitors CA, CB having values closely resembling distributed capacity CP, CQ existing in parallel with the resistors are mounted among each output terminal A.B and a neutral point O of a Cockcroft type boosting rectifying circuit.

Inventor: NAMITA HIROMITSU
IPC: H01L21/316
Filed: 1991-06-11
Abstract: PURPOSE:To make a inter-layer insulating film to have a good flatness by a method wherein the inter-layer insulating film is formed on the uneven surface of a semiconductor substrate and the surface of the inter-layer insulating film is etched after energy beam is applied. CONSTITUTION:After a silicon oxide film 2 is deposited on a silicon substrate 1, a step is formed with a polysilicon film 3 and then a BPSG film 4 is deposited. Nextly, electron beam 5 having the uniform intensity is applied as an energy beam to the entire surface of the substrate. Then, the substrate is etched in an etchant which is a mixture of hydrofluoric acid and pure water to flatten the surface of the BPSG film 4. After that, the substrate is heat- treated in nitrogen to smooth the BPSG film and to make the quality of the film uniform. Consequently, the etching rate is larger in the protruding part of the inter-layer insulating film than in the recessed part. Therefore, the flattening of the semiconductor substrate can be performed by optimizing the thickness of the inter-layer insulating film.

Abstract: PURPOSE:To enable heat which is generated at a stator core to be dissipated quickly by providing a plurality of cooling fins only at a part corresponding to an arc part of a stator core of an outer peripheral part of a machine frame for increasing cooling area of a part corresponding to the arc part of the stator core of the machine frame. CONSTITUTION:A plurality of cooling fans 36a-36e are provided at a part corresponding to an arc part 26d of a stator core 26 of a stator frame 21 so that cooling area of a part corresponding to the arc part 26d where heat can be easily transmitted out of an outer peripheral part of the stator core 21 can be increased. Thus, heat of the stator core 26 which is transmitted to the stator frame 21 through the arc part 26d is dissipated rapidly from a plurality of cooling fins 36a-36e into air, thus enabling temperature increase of the stator frame 21 and the stator core 26 to be reduced and temperature at each part to be uniform. Especially, since the height dimensions of the central cooling fin 36e of the stator core 26 are formed to be the maximum, temperature increase can be reduced effectively.

Title: Negative-pressure source device of negative-pressure type booster for car
Inventor: TAKEUCHI HIROO
IPC: B60T17/02
Filed: 1983-07-28
Abstract: PURPOSE:To shrink the pressure receiving area of a booster, make the magnifier smaller, and accelerate the storage of a negative pressure by operating an air ejector by the intake negative pressure of an internal-combustion engine and applying the high intake negative pressure generated in its decompression chamber to the negative-pressure chamber of the booster. CONSTITUTION:While an internal-combustion engine is in operation, the intake negative pressure generated downstream a throttle valve is applied to the outlet chamber 16 of an air ejector 10 and a bypass 22 via a negative-pressure passage 9. The negative pressure applied to the bypass 22 opens the first check valve 23, then it proceeds to open the second check valve 24, and it reaches a negative pressure chamber 3 partitioned by a diaphragm in a negative pressure type booster S via an intake port 14 and is stored here. On the other hand, the negative pressure applied to an outlet chamber 16 is applied to the nozzle hole of a nozzle 21 via a diffuser 17, and air is absorbed through the nozzle 21, thus decompressing a decompression chamber 15. When the negative pressure in the decompression chamber 15 becomes higher than the said intake negative pressure and the check valve 23 is opened, the negative pressure is guided into the negative-pressure chamber 3.

Filed: 1989-05-31
Abstract: PURPOSE:To manufacture a semiconductor device having flattened patterns in projection shape by a method wherein the whole projecting patterns formed on a substrate is simultaneously exposed regardless of the existence of any rugged and stepped parts on the substrate. CONSTITUTION:An SiO2 film 3 is deposited in the same thickness as that of metallic wirings 2 by CVD process on the whole surface. The whole surface coated with a photoresist 4 is patterned to form openings 5 above the wirings 2. The SiO2 film 3 beneath the openings 5 is removed by HF base wet etchant using a photoresist pattern as a mask. After removing the resist 4, grooves are made between the metallic wirings 2 and the SiO2 film 3. Next, the resist 4 is removed to deposit another SiO2 film 3A by CVD process again. This film 3A is deposited to fill up the grooves between the wirings 2 and the film 3 so that the surface ruggedness due to these grooves may be made almost inconspicuous when this film 3A is deposited exceeding specific thickness. Finally, the SiO2 film 3A is dryetched using CF4 base gas to simultaneously expose the metallic wiring 2.
